Potato flowers, like all members of the nightshade family, are a thing of tiny beauty. They are also a flag to signal that below the ground, the tubers are starting to swell and need as much water as you can give them, especially in dry spells.

#wildflowerhour takes place every Sunday between 8-9pm on Twitter, Facebook and Instagram. Just add #wildflowerhourto your posts about the flowers you've found growing wild in Britain and Ireland in the previous week, and enjoy an hour of beauty and happiness. And if you don't recognise a flower, post it and our wonderful community of experts and amateur botanists will help ID it.
